Abstract
A power management system for a personal area fabric having a plurality of nodes is presented. The system implements power management functions at the fabric-level via fabric-level power profiles reflecting the aggregated power profiles from some or all of the nodes in the fabric. The fabric-level power profiles are used to trigger the implementation of fabric power configurations that cause the individual nodes to modify their operations in the interest of a fabric-level power management plan.
Claims39
A personal area fabric, comprising:
- a plurality of networked nodes, wherein each networked node comprises a node power profile and a short range communication interface configured to exchange data with at least one other networked node of the plurality of networked nodes and wherein each networked node is positioned to be able receive communication via the short range communication interface from at least one other networked node of the plurality of networked nodes;
- wherein at least one of the plurality of networked nodes has a state configuration engine configured to, when executed by a processor:
- receive a power configuration trigger;
- aggregate node power profiles from a portion of the plurality of networked nodes;
- derive a fabric-level power configuration as a function of the aggregated node power profiles by designating a subset of the portion of the plurality of networked nodes as boundary nodes, wherein the fabric-level power configuration only allows communication outside the personal area fabric via at least one of the boundary nodes;
- and
- instruct the portion of the plurality of networked nodes to operate according to the fabric-level power configuration in response to the power configuration trigger.

A personal area fabric, comprising:
- a plurality of networked nodes, wherein each networked node comprises at least one short range communication interface configured to exchange data with at least one other networked node among the plurality of networked nodes and wherein each networked node is positioned to be able receive communication via the short range communication interface from at least one other networked node of the plurality of networked nodes;
- wherein at least one of the plurality of networked nodes further comprises a sensor;
- wherein at least one of the plurality of networked nodes includes two or more operating power states;
- wherein at least one of the plurality of the networked nodes includes a node power profile;
- wherein at least one of the plurality of networked nodes further comprises a non-transient computer readable memory, a processor, and computer readable instructions configured to, when executed by said processor:
- receive data from a sensor of at least one of the plurality of networked nodes;
- derive a fabric-level power configuration of the plurality of networked nodes as a function of one or more node power profiles by designating a subset of the portion of the plurality of networked nodes as boundary nodes, wherein the fabric-level power configuration only allows communication outside the personal area fabric via at least one of the boundary nodes;
- and
- instruct, in response to sensor data, at least one of the plurality of networked nodes to operate at an operating power state as a function of the derived power configuration.
